Qucs for MAC

Qucs It is an integrated circuit simulator that allows you to set up a circuit using a graphical user interface (GUI), and simulate its large-signal, small signal, and noise behaviour. Once the simulation is complete, you can view the results on a presentation page.

Qucs stands for Quite Universal Circuit Simulator. It is a circuit simulator that uses a graphical user interface (GUI). The GUI is built on Qt(r), by Trolltech(r). The software supports all types of circuit simulation types, such as. DC, AC and S-parameter are supported.

The simulation backend is Qucsator. It simulates command-line circuits. It accepts a network list of a particular format as input and outputs Qucs data. It was programmed for use in the Qucs project, but can also be used by other applications. We were currently working on the GUI and some basic simulation features. There is now a user interface that allows you to set up schematics and present simulation results in different types of diagrams. You can do DC, AC, S,parameter, noise, and transient analysis. There are also mathematical equations and the use of a subcircuit tree hierarchy. However, there is still a lot to do and we are looking for people to help us.
